During a shutdown for a major power provider, CCI cleaned every section of 3 Riley Stoker boilers. CCI used the latest technologies in Hydro-blasting to clean the more difficult sections of these boilers. All wash water from this project was contained using spill berms collected using vac trucks. These vac trucks were then systematically offloaded into Frac tanks that were placed at a different parts of the site. CCI also used the vac trucks to vacuum out the grate plenum, generating bank, and economizer inlet of each boiler. The waste water and debris vacuumed up by CCI was then classified and disposed of by CCI. Pictured to the right are the 2 hydro blasters used for this project.
CCI cleaned a vertical 40,000 gallon above ground storage tank and removed the above and below ground fuel lines associated with it. CCI also removed 5,000 gallons of non-hazardous #6 oil and sludge material that was left inside. A vac truck was used by CCI personnel to vacuum out the 40,000 gallon tank. The fuel oil that could not be vacuumed out was pressure washed, squeegeed, and dried the tank by confined space personnel. CCI technicians vacuumed out the fuel lines and flushed the lines with diesel fuel. The lines were then pressure washed to further clean the fuel lines. Lastly, a number 3” pig was pushed through the fuel lines to verify that the lines were clean and clear. The overhead lines were cut and removed, and the underground lines were excavated. Void space created by the excavations for the fuel lines was backfilled with clean earth backfill. The above and below ground fuel lines were cut again to be placed into open top roll-off boxes for transportation and disposal. All fuel oil waste and wash water associated with this project was containerized in vac truck for transportation and proper disposal.
CCI cleaned out and washed a 70,000 gallon above ground storage tank that was used to store Butyl Acetate. Before the work started, CCI prepared a job specific JHA. CCI then proceeded to clean the inside of a butyl acetate above ground storage tank. The product remaining in the tank was vacuumed out using our CCI vac truck. The tank walls were then cleaned using a 3D tank cleaning tool. CCI then made a confined space entry to pressure was the tank’s floors and to insure the tanks cleanliness. A three man confined space rescue team provided by CCI was placed on standby on this project. All waste previously in the tank and wash water used to clean the tank was properly manifested and disposed of.
